L-Glutamine has been a tough sell for me, until some of the manufacturers actually started making a REAL MICRONIZED version.
This is the stuff, mixes about the best of all of them, and the added MSM is perfect for those of us who lift heavy.
A scoop or two in every PW shake will be unnoticeable tastewise, but definitely helps with recovery.
Like most of their products, IDS hits the bullseye with this one.

This product works great. I have been using this product for years off and on; mainly during tours to Iraq. Glutamine is essential in the recovery of sore muscles along with simple stretching to get the lactic acid out of the muscle and out to the blood stream. IDS just offers the best price for the most amount. Now the taste leaves much to be desired; but I mix it with something sweet to mask the taste. The bottom line is that you wont be afraid to go big for fear of being sore with this in your diet; it's like a hangover cure for sore muscles.
